@ak0ztik Most educated people know both incest and cannibalism. Not widely know? What? And yes, incest occurs quite frequently, especially in manga and the like. But incest between close relatives, like parent-child or between siblings, is still a
huge social taboo in actual real life. Abel already spent a childhood with those norms, and he knows the (potential) bad effects of incestous children. To him, incest might as well be just as disgusting as cannibalism is monstrous.
Regardless, his family and clan put him in such an uncomfortable situation, under such pressure, that he felt he had no choice but to run away and be forever an outcast. He's the
victim in all of this! And he didn't actually "just" run away, he left a letter explaining what he did and why, and his dad knows he didn't want to marry Gizel. Gizel on the other hand didn't confront him, even though she knew what he would do, but rather hid the letter and sabotaged his cart. In such a way that he either died, or returned to live in disgrace.
Ponder if Abel
didn't run away, and tried to talk it out. His dad already proved he wouldn't listen, and just forced the issue harder. His mom doesn't seem to care much at all. Gizel has now proven herself to be quite unhinged. His entire clan thinks incest marriage is normal and expected. Do you think
anyone would listen? What other way was there? If you have suggestions I would love to hear them.
